Title: Machines having Safety Guards, and Control Mechanisms therefor.
Inventor: HARFIELD MICHAEL WILLIAM
IPC: F16P3/00
Filed: 1966-04-07
Abstract: 1,179,112. Machinery safety devices. DRAGONAIR Ltd. 31 March, 1967 [7 April, 1966], No. 15763/66. Heading F2J. In a safety device for a press brake, wherein fluid control valves 6, 15, sensitive to the positions of a pressing bed 2 and a pivoted guard 12 respectively, control a mechanical interlock for a lever 17 controlling movement of the pressing bed, the lever 17 cannot be moved to initiate a pressing operation until, with the guard 12 in its safe position (shown dotted, Fig. 1), the bed 2 has been brought to a preoperative position close enough to a blade 3 to prevent insertion of an operator's hand, &c., therebetween but just permitting insertion of a workpiece. Initially the bed 2 is in its lowest position, the guard 12 is lowered (solid lines, Fig. 1), and the lever 17 is in its central, neutral position. Pins 22, 23 on a plate 21 secured to the lever 17 engage surfaces 35, 34 of a lever 25 pivoted on trunnions 26 and connected at 30 to hydraulic valves (not shown) controlling press operation. A pawl 41 engaging a notch 24 in the plate 21 prevents movement of lever 17 in direction A. The guard 12 is raised to its safe position, causing an arm 13 to open a valve 15 to admit compressed air to a cylinder 53 so that a pin 51 on the piston-rod 52 is moved upwards (Fig. 2) to act via a bell-crank 47 to move a bar 33 leftwards, a pin 49 thereon sliding in a horizontal slot. A step 32 on the bar 33 engages a dog 31 on the lever 25 to pivot the latter to raise the bed 2. When the bed reaches its pre-operative position an adjustable striker 5 operates a valve 6 to admit compressed air to a cylinder 46, the piston-rod 45 of which engages a pin 44 on a pivoted lever 28 carrying the pawl 41. The lever 28 is rocked to move pawl 41 out of notch 24 to unlock the lever 17, and a projection 42 on lever 28 engages a part 43 of the bar 33 to raise the step 32 clear of the dog 31, allowing the lever 25 to return to its neutral position to stop the bed 2 from rising. The guard 12 is lowered, closing valve 15 and venting cylinder 53 to withdraw the bar 33, and a workpiece is loaded between the bed 2 and the blade 3. The press is operated by moving lever 17 in direction A, and, on lowering of the pressing bed at the end of the operation, the valve 6 is closed, allowing pawl 41 to reengage notch 24 to prevent subsequent raising of the bed 2 without raising the guard 12 to its safe position.

Title: Method and apparatus for cathodic protection of ship hulls in sea water by electron concentration
IPC: B63B59/04
Filed: 1958-05-19
Abstract: 842,297. Preventing corrosion. OBERMANN, W. May 19, 1958 [June 4, 1957], No. 15964/58. Class 123(1) In an impressed current system for the cathodic protection of a ship's hull, the negative potential applied to the hull is sufficient to provide the necessary protection without polarization of the hull. In the apparatus used each anode is insulated from the hull by a dielectric panel and is connected to a source of low voltage direct current exceeding three volts and capable of supplying a current ranging from 0À05 milliamperes per square foot of submerged hull surface to less than the current density which would result in a back e.m.f. on the hull exceeding 0À70 volts to a saturated calomel half cell, each anode to have an interface resistance of at least 0-45 ohms with sea water of the Gulf Stream. Electron concentration in the negative part of the circuit forces electrons to all over the surface of the hull and anodic points are protected, all the area being cathodic. In operation, the flow of current for the high resistance anodes is not sufficient to maintain polarization of the hull which potential will remain at the level of freely corroding steel i.e. 0À55 volts in sea water. The anode assembly is mounted on a dielectric panel 24 to insulate the anode from the hull and the anode 14, Fig. 2A, is mounted in a casing 28 made of dielectric material or having a dielectric liner 30 therein, the anode being located between structural channels 29 of the hull 10. The casing 28 is welded at 32 to plate 20 of the hull and the anode passes through opposite walls of the casing, being held in position to allow contact with the sea water. The anode is connected by wires 34 which lead into the ship through a junction bore 36 to a regulated low voltage D.C. power supply 38 so that a predetermined voltage will cause current to flow from the anode to the sea water.
